Title: Serial digital signal processing circuitry
IPC: H03M1/00
Filed: 1987-03-17
Abstract: A serial-bit digital processing system uses registers and latches to synchronize samples and justify sign-bits. Nominally each processing block in the system includes a sign extend register (16) preceding an arithmetic element (18) and an output register (20) following the arithmetic element. Input registers of one arithmetic element may merge with output registers of the preceding arithmetic element. The sign extend registers include a serially coupled latch which is selectively controlled to pass serial sample bits or to replicate the sign bit. The respective registers are clocked with one of two clock signals (CLOCKN, CLOCKP) having different numbers of pulses per sample period and the length of the respective registers are selected so that at the terminus of each sample period the bits of each sample in the processing system are appropriately justified.

Patent EP-0267721-A3 (EP)
IPC: G03F9/00
Filed: 1987-11-02
Abstract: A reticle design is provided for step and repeat 
projection aligners which, when patterned on a wafer (10), 
allows quick macroscopic evaluation of best focus for used 
in fabricating integrated circuits. The reticle pattern 
consists of opaque lines and spaces of widths slightly 
above the resolution limit of the resist/aligner system.  
     The macroscopic determination of best focus, being 
macroscopically visible, eliminates the need for micro­
scopic determination, thereby providing a quick and easy 
method. The best focus determination is made by forming 
an array (22) of resist fields (14′) on the wafer, sub­
jecting each field to a different focus and exposure. 
Upon development, those fields away from the best focus 
and at the larger exposure doses will be removed, leaving 
a parabola (24) of fields whose apex (26) is at high 
exposure. Best focus is the focus setting used to print 
the row of fields (B) containing the apex. The procedure 
may be used at different lens locations and reticle orien­
tations to quantify lens aberrations and field tilt.  
     The method of the invention is also suitably used to 
qualitatively and quantitatively diagnose and characterize 
the lens, by printing full fields (34) with varying focus. 
In this manner, lens astigmatism and curvature and field 
tilt can be mapped, measured, and understood.

Filed: 1987-11-23
Abstract: A drill bit for drilling deep holes in 
subsurface formations comprises a bit body 10 having a 
generally hemispherical leading face 11 and a gauge region 
12, and two blades 13 each extending spirally outwardly 
across the leading face of the bit body away from the axis 
of rotation, a cavity 16 of substantial peripheral and 
axial extent being formed in the bit body on the forward 
side of each blade, and communicating with an associated 
exit channel 19 in the gauge region. A plurality of 
cutting elements 22 are mounted along each blade 13, the 
cutting elements being mounted closely adjacent one 
another side-by-side along the blade so that their cutting 
edges together form a single long cutting edge without 
substantial discontinuities. A passage 9 in the bit body 
supplies drilling fluid to nozzles 21 in the cavities 16 
for cooling and cleaning the cutting elements 22, fluid 
from the nozzles sweeping past the cutting elements and 
out through the exit channels 19.

IPC: C10G47/16
Filed: 1987-12-03
Abstract: A moderate pressure hydrocracking process in which a highly 
aromatic, substantially dealkylated feedstock boiling between 149 
and 343°C (300°C and 650°F) is processed directly to high octane 
gasoline by hdrocracking over a catalyst, preferably comprising a 
large pore size, crystalline alumino-silicate zeolite hydrocracking 
catalyst such as zeolite Y together with a hydrogenation-­
dehydrogenation component. The feedstock which is preferably a 
light cut light cycle oil has an aromatic content of at least 50, 
usually at least 60 wt % and a density of at least 0.93 g/cc (an API 
gravity not more than 25). The hydrocracking typically operates at 
4200-7000 kPa (600-1000 psig) at moderate to high conversion 
levels to maximize the production of monocyclic aromatics which 
provide the requisite octane value to the product gasoline.

Title: Automatic transmission shift control device
IPC: F16H59/10
Filed: 1988-10-14
Abstract: A position pin (20) is pushed down by an effort applied on a control button (27) to disengage the position pin (20) from a position plate (18) when a selector lever is to be moved from a parking position to other gear positions. A bushing (28) is mounted on a post (14) of the selector lever for rotation but against axial movement. The bushing has at the upper end a pair of diameterically opposed notches (29) with which the position pin is engaged when pushed down to effect the above disengagement. When an ignition key is at the "ON" position and the selector lever is at the parking position, the bushing is rotated into a position where the notches are misaligned with the position pin unless a brake pedal is fully depressed, i.e., an effor applied on the control button for pushing the position pin downward is received by the upper end of the bushing whereby downward movement of the position pin for disengagement thereof from the position plate is prevented by the bushing and therefore it is impossible to move the selector lever from the parking position to other gear positions. In accordance with the present invention, there are further provided various safety means for preventing the positon pin from being errorneously aligned with the notches.

Abstract: A method for immunoassay of a viral antigen is 
performed on a membrane precoated with an inert 
protein. Nonimmunological capture of antigen takes 
place by absorption onto the coated membrane. 
Captured antigen binds to a tracer which includes a 
label conjugated to a specific antibody, the inert 
protein concomitantly inhibiting nonspecific binding 
of tracer. The label may be an enzyme which converts 
a substrate to a detectable product or converts a 
blocked inhibitor to an inhibitor whereby a second 
enzyme is inhibited from converting a substrate to a 
product. The invention includes a kit of materials 
for performing an assay in accordance with the method 
of the invention.
